LUBRICATING- DEVICE.

Specification of Letters Patent.

latented A r-.6, 1915.

Application filed June 23, 1914. Serial No. 846,838.

To all uzhom. it may concern.-

Be it known that I, HENNING LIND, a citizen of the United States, residing at T- peka, in the county of Shawnee and State of Kansas, have invented new and useful' Improvements in Lubricating Devices, of which the following is a specification.

This invention relates to lubricating devices, and it has particular reference to lubricating devices for machine parts, such as pitman boxes for mowing machines and the like from which, owing to the constant jerking motion of the parts the contents of the oil receptacle is in danger of being spilled and where an ordinary screw plug or stopper is not found effective owing to the danger of its being loosened and lost.

The present invention has for its object to produce a lubricating device embodying a receptacle which is integral with a machine part, such as a boxing, and which is provided with a simple and effective covering device.

A further object of the invention is to simplify and improve the construction and operation of the cover for the lubricating receptacle.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,Figure 1 is a top plan view of the pitman boxing constructed in the bore 16 for engagement with the pitman which is also not shown. One side of the boxing has a lug or projection 18 provided with a well or receptacle 19which communicates with the bore 16 through a duct or channel 20. The well 19 constitutes a lubricant receptacle, the contents of which may pass through the duct 20 to the bearing that is to be lubricated.

The lug 18 is provided with an upwardly extending pin or stud 21 which is securely embedded in or connected therewith, said pin having a head 22 at the upper end thereof. Mounted on the pin 21 is a cover plate 23 having upturned end flanges 2 1 that project terminally beyond the side edges of the face of the lug 18 which constitutes the body portion in which the well 19 is formed, said flanges serving to enable the cover plate to be readily grasped and manipulated. A spring 25 which is coiled on the pin 21 between the head 22 and the cover plate 23 serves to force the latter downwardly against the top face of the lug 18. The pin 21 extends upwardly from'the lug 18 in spaced relation to the well 19, as will be clearly seen in Fig. 2. The cover plate is provided on its under face with a plug 26 which is suitably positioned to engage the upper end of the well 19 wherein it fits snugly, and which will be securely stoppered by said plug.

It will be readily seen that when the plug is in'engagement with the upper end of the well, the part-s will be retained securely in the desired relative position by the action of the spring 25. When it shall be desired to replenish the contents of the well, the stopper plate is lifted against the tension of the springs su'fiiciently to disengage the plug 26 from the well, after which the stopper plate may be turned about the axis of the pin 21 to the position shown in Fig. 3 of the drawings, leaving the well conveniently accessible. By a swinging movement of the plug carrying end of the stopper plate, the latter being at the same time slightly lifted against the tension of the spring, the parts may be quickly restored to the former position which is indicated in Fig. 2, when the plug will securely close the top of the well.

It will be seen that owing to the construction of the cover plate 23 with the upturned flanges 24, downward pressure on the outermost of said flanges will result in tipping the boxing may be shaken or vibrated by operation of the machine of which it forms a part, it is'quite impossible for the parts to become disarranged, and loss of lubricating material from such cause will be completely avoided.

Having thus described the invention, What is claimed as new, is

A body member having a well formed therein and constituting an oil receptacle, a

Copies of this patent may be obtained for five cents each, by addressing the from the top face of said relation to the Well, a cover plate pivoted on said pin for vertical slidable movement thereon, said plate having upturned end flanges whereby it may be manipulated, one of said end flanges proheaded pin rising member in spaced jecting beyond the body member to enable the cover plate to be tilted by downward pressure on said flange, a plug on the under face of the cover plate fitting the upper end of the well and constituting a closure for the same and also an obstruction to resist pivotal movement of the plate, and a spring coiled on the pin between the head and the cover plate and exerting downward pressure on the latter.

In testimony whereof I affix my signature in presence of two witnesses.

HENNING LIND.
